The following files I obtained from a site (that is down atm, but will post site if/once it goes back up). It is the Corporate flashing utility for the Samsung R720 (EH02) for programming the phone to the cricket Networks port of 2.3.4. The original PST software with the pack did not work, so I've added a PST software that is compatible. Disclaimer: I am in no way responsible for bricking of devices -- Use at your own risk! Here is the pack below. Samsung R720 Cricket.zip Mirror. http://openzio.rtrnetwork.com/openzio/openvitality/Samsung R720 Cricket.zip Unzip to a folder, and follow the directions below. *note: You may get an error during flashing stating something about not being able to access a log file. After passing through that, the flash should continue as normal. Please report results/comments/questions to this thread. ~Cheers!
